-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or

-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-Implementation notes regarding ADB.
-
-I. General Overview:
-
-The Android Debug Bridge (ADB) is used to:
-
-- keep track of all Android devices and emulators instances
-  connected to or running on a given host developer machine
-
-- implement various control commands (e.g. "adb shell", "adb pull", etc.)
-  for the benefit of clients (command-line users, or helper programs like
-  DDMS). These commands are called 'services' in ADB.
-
-As a whole, everything works through the following components:
-
-  1. The ADB server
-
-    This is a background process that runs on the host machine. Its purpose
-    is to sense the USB ports to know when devices are attached/removed,
-    as well as when emulator instances start/stop.
-
-    It thus maintains a list of "connected devices" and assigns a 'state'
-    to each one of them: OFFLINE, BOOTLOADER, RECOVERY or ONLINE (more on
-    this below).
-
-    The ADB server is really one giant multiplexing loop whose purpose is
-    to orchestrate the exchange of data (packets, really) between clients,
-    services and devices.
-
-
-  2. The ADB daemon (adbd)
-
-    The 'adbd' program runs as a background process within an Android device
-    or emulated system. Its purpose is to connect to the ADB server
-    (through USB for devices, through TCP for emulators) and provide a
-    few services for clients that run on the host.
-
-    The ADB server considers that a device is ONLINE when it has successfully
-    connected to the adbd program within it. Otherwise, the device is OFFLINE,
-    meaning that the ADB server detected a new device/emulator, but could not
-    connect to the adbd daemon.
-
-    The BOOTLOADER and RECOVERY states correspond to alternate states of
-    devices when they are in the bootloader or recovery mode.
-
-  3. The ADB command-line client
-
-    The 'adb' command-line program is used to run adb commands from a shell
-    or a script. It first tries to locate the ADB server on the host machine,
-    and will start one automatically if none is found.
-
-    Then, the client sends its service requests to the ADB server.
-
-    Currently, a single 'adb' binary is used for both the server and client.
-    this makes distribution and starting the server easier.
-
-
-  4. Services
-
-    There are essentially two kinds of services that a client can talk to.
-
-    Host Services:
-      These services run within the ADB Server and thus do not need to
-      communicate with a device at all. A typical example is "adb devices"
-      which is used to return the list of currently known devices and their
-      states. They are a few other services though.
-
-    Local Services:
-      These services either run within the adbd daemon, or are started by
-      it on the device. The ADB server is used to multiplex streams
-      between the client and the service running in adbd. In this case
-      its role is to initiate the connection, then of being a pass-through
-      for the data.
-
-
-II. Protocol details:
-
-  1. Client <-> Server protocol:
-
-    This details the protocol used between ADB clients and the ADB
-    server itself. The ADB server listens on TCP:localhost:5037.
-
-    A client sends a request using the following format:
-
-        1. A 4-byte hexadecimal string giving the length of the payload
-        2. Followed by the payload itself.
-
-    For example, to query the ADB server for its internal version number,
-    the client will do the following:
-
-        1. Connect to tcp:localhost:5037
-        2. Send the string "000Chost:version" to the corresponding socket
-
-    The 'host:' prefix is used to indicate that the request is addressed
-    to the server itself (we will talk about other kinds of requests later).
-    The content length is encoded in ASCII for easier debugging.
-
-    The server should answer a request with one of the following:
-
-        1. For success, the 4-byte "OKAY" string
-
-        2. For failure, the 4-byte "FAIL" string, followed by a
-           4-byte hex length, followed by a string giving the reason
-           for failure.
-
-    Note that the connection is still alive after an OKAY, which allows the
-    client to make other requests. But in certain cases, an OKAY will even
-    change the state of the connection.
-
-    For example, the case of the 'host:transport:<serialnumber>' request,
-    where '<serialnumber>' is used to identify a given device/emulator; after
-    the "OKAY" answer, all further requests made by the client will go
-    directly to the corresponding adbd daemon.
-
-    The file SERVICES.TXT lists all services currently implemented by ADB.
-
-
-  2. Transports:
-
-    An ADB transport models a connection between the ADB server and one device
-    or emulator. There are currently two kinds of transports:
-
-       - USB transports, for physical devices through USB
-
-       - Local transports, for emulators running on the host, connected to
-         the server through TCP
-
-    In theory, it should be possible to write a local transport that proxies
-    a connection between an ADB server and a device/emulator connected to/
-    running on another machine. This hasn't been done yet though.
-
-    Each transport can carry one or more multiplexed streams between clients
-    and the device/emulator they point to. The ADB server must handle
-    unexpected transport disconnections (e.g. when a device is physically
-    unplugged) properly.

-This file tries to document all requests a client can make
-to the ADB server of an adbd daemon. See the OVERVIEW.TXT document
-to understand what's going on here.
-
-HOST SERVICES:
-
-host:version
-    Ask the ADB server for its internal version number.
-
-host:kill
-    Ask the ADB server to quit immediately. This is used when the
-    ADB client detects that an obsolete server is running after an
-    upgrade.
-
-host:devices
-host:devices-l
-    Ask to return the list of available Android devices and their
-    state. devices-l includes the device paths in the state.
-    After the OKAY, this is followed by a 4-byte hex len,
-    and a string that will be dumped as-is by the client, then
-    the connection is closed
-
-host:track-devices
-    This is a variant of host:devices which doesn't close the
-    connection. Instead, a new device list description is sent
-    each time a device is added/removed or the state of a given
-    device changes (hex4 + content). This allows tools like DDMS
-    to track the state of connected devices in real-time without
-    polling the server repeatedly.
-
-host:emulator:<port>
-    This is a special query that is sent to the ADB server when a
-    new emulator starts up. <port> is a decimal number corresponding
-    to the emulator's ADB control port, i.e. the TCP port that the
-    emulator will forward automatically to the adbd daemon running
-    in the emulator system.
-
-    This mechanism allows the ADB server to know when new emulator
-    instances start.
-
-host:transport:<serial-number>
-    Ask to switch the connection to the device/emulator identified by
-    <serial-number>. After the OKAY response, every client request will
-    be sent directly to the adbd daemon running on the device.
-    (Used to implement the -s option)
-
-host:transport-usb
-    Ask to switch the connection to one device connected through USB
-    to the host machine. This will fail if there are more than one such
-    devices. (Used to implement the -d convenience option)
-
-host:transport-local
-    Ask to switch the connection to one emulator connected through TCP.
-    This will fail if there is more than one such emulator instance
-    running. (Used to implement the -e convenience option)
-
-host:transport-any
-    Another host:transport variant. Ask to switch the connection to
-    either the device or emulator connect to/running on the host.
-    Will fail if there is more than one such device/emulator available.
-    (Used when neither -s, -d or -e are provided)
-
-host-serial:<serial-number>:<request>
-    This is a special form of query, where the 'host-serial:<serial-number>:'
-    prefix can be used to indicate that the client is asking the ADB server
-    for information related to a specific device. <request> can be in one
-    of the format described below.
-
-host-usb:<request>
-    A variant of host-serial used to target the single USB device connected
-    to the host. This will fail if there is none or more than one.
-
-host-local:<request>
-    A variant of host-serial used to target the single emulator instance
-    running on the host. This will fail if there is none or more than one.
-
-host:<request>
-    When asking for information related to a device, 'host:' can also be
-    interpreted as 'any single device or emulator connected to/running on
-    the host'.
-
-<host-prefix>:get-product
-    XXX
-
-<host-prefix>:get-serialno
-    Returns the serial number of the corresponding device/emulator.
-    Note that emulator serial numbers are of the form "emulator-5554"
-
-<host-prefix>:get-devpath
-    Returns the device path of the corresponding device/emulator.
-
-<host-prefix>:get-state
-    Returns the state of a given device as a string.
-
-<host-prefix>:forward:<local>;<remote>
-    Asks the ADB server to forward local connections from <local>
-    to the <remote> address on a given device.
-
-    There, <host-prefix> can be one of the
-    host-serial/host-usb/host-local/host prefixes as described previously
-    and indicates which device/emulator to target.
-
-    the format of <local> is one of:
-
-        tcp:<port>      -> TCP connection on localhost:<port>
-        local:<path>    -> Unix local domain socket on <path>
-
-    the format of <remote> is one of:
-
-        tcp:<port>      -> TCP localhost:<port> on device
-        local:<path>    -> Unix local domain socket on device
-        jdwp:<pid>      -> JDWP thread on VM process <pid>
-
-    or even any one of the local services described below.
-
-<host-prefix>:forward:norebind:<local>;<remote>
-    Same as <host-prefix>:forward:<local>;<remote> except that it will
-    fail it there is already a forward connection from <local>.
-
-    Used to implement 'adb forward --no-rebind <local> <remote>'
-
-<host-prefix>:killforward:<local>
-    Remove any existing forward local connection from <local>.
-    This is used to implement 'adb forward --remove <local>'
-
-<host-prefix>:killforward-all
-    Remove all forward network connections.
-    This is used to implement 'adb forward --remove-all'.
-
-<host-prefix>:list-forward
-    List all existing forward connections from this server.
-    This returns something that looks like the following:
-
-       <hex4>: The length of the payload, as 4 hexadecimal chars.
-       <payload>: A series of lines of the following format:
-
-         <serial> " " <local> " " <remote> "\n"
-
-    Where <serial> is a device serial number.
-          <local>  is the host-specific endpoint (e.g. tcp:9000).
-          <remote> is the device-specific endpoint.
-
-    Used to implement 'adb forward --list'.
-
-LOCAL SERVICES:
-
-All the queries below assumed that you already switched the transport
-to a real device, or that you have used a query prefix as described
-above.
-
-shell:command arg1 arg2 ...
-    Run 'command arg1 arg2 ...' in a shell on the device, and return
-    its output and error streams. Note that arguments must be separated
-    by spaces. If an argument contains a space, it must be quoted with
-    double-quotes. Arguments cannot contain double quotes or things
-    will go very wrong.
-
-    Note that this is the non-interactive version of "adb shell"
-
-shell:
-    Start an interactive shell session on the device. Redirect
-    stdin/stdout/stderr as appropriate. Note that the ADB server uses
-    this to implement "adb shell", but will also cook the input before
-    sending it to the device (see interactive_shell() in commandline.c)
-
-remount:
-    Ask adbd to remount the device's filesystem in read-write mode,
-    instead of read-only. This is usually necessary before performing
-    an "adb sync" or "adb push" request.
-
-    This request may not succeed on certain builds which do not allow
-    that.
-
-dev:<path>
-    Opens a device file and connects the client directly to it for
-    read/write purposes. Useful for debugging, but may require special
-    privileges and thus may not run on all devices. <path> is a full
-    path from the root of the filesystem.
-
-tcp:<port>
-    Tries to connect to tcp port <port> on localhost.
-
-tcp:<port>:<server-name>
-    Tries to connect to tcp port <port> on machine <server-name> from
-    the device. This can be useful to debug some networking/proxy
-    issues that can only be revealed on the device itself.
-
-local:<path>
-    Tries to connect to a Unix domain socket <path> on the device
-
-localreserved:<path>
-localabstract:<path>
-localfilesystem:<path>
-    Variants of local:<path> that are used to access other Android
-    socket namespaces.
-
-framebuffer:
-    This service is used to send snapshots of the framebuffer to a client.
-    It requires sufficient privileges but works as follow:
-
-      After the OKAY, the service sends 16-byte binary structure
-      containing the following fields (little-endian format):
-
-            depth:   uint32_t:    framebuffer depth
-            size:    uint32_t:    framebuffer size in bytes
-            width:   uint32_t:    framebuffer width in pixels
-            height:  uint32_t:    framebuffer height in pixels
-
-      With the current implementation, depth is always 16, and
-      size is always width*height*2
-
-      Then, each time the client wants a snapshot, it should send
-      one byte through the channel, which will trigger the service
-      to send it 'size' bytes of framebuffer data.
-
-      If the adbd daemon doesn't have sufficient privileges to open
-      the framebuffer device, the connection is simply closed immediately.
-
-jdwp:<pid>
-    Connects to the JDWP thread running in the VM of process <pid>.
-
-track-jdwp
-    This is used to send the list of JDWP pids periodically to the client.
-    The format of the returned data is the following:
-
-        <hex4>:    the length of all content as a 4-char hexadecimal string
-        <content>: a series of ASCII lines of the following format:
-                        <pid> "\n"
-
-    This service is used by DDMS to know which debuggable processes are running
-    on the device/emulator.
-
-    Note that there is no single-shot service to retrieve the list only once.
-
-sync:
-    This starts the file synchronization service, used to implement "adb push"
-    and "adb pull". Since this service is pretty complex, it will be detailed
-    in a companion document named SYNC.TXT
-
-reverse:<forward-command>
-    This implements the 'adb reverse' feature, i.e. the ability to reverse
-    socket connections from a device to the host. <forward-command> is one
-    of the forwarding commands that are described above, as in:
-
-      list-forward
-      forward:<local>;<remote>
-      forward:norebind:<local>;<remote>
-      killforward-all
-      killforward:<local>
-
-    Note that in this case, <local> corresponds to the socket on the device
-    and <remote> corresponds to the socket on the host.
-
-    The output of reverse:list-forward is the same as host:list-forward
-    except that <serial> will be just 'host'.

-to understand what's going on here. See the SERVICES.TXT to learn more
-about the other requests that are possible.
-
-SYNC SERVICES:
-
-
-Requesting the sync service ("sync:") using the protocol as described in
-SERVICES.TXT sets the connection in sync mode. This mode is a binary mode that
-differs from the regular adb protocol. The connection stays in sync mode until
-explicitly terminated (see below).
-
-After the initial "sync:" command is sent the server must respond with either
-"OKAY" or "FAIL" as per usual.
-
-In sync mode both the server and the client will frequently use eight-byte
-packets to communicate. In this document these are called sync requests and sync
-responses. The first four bytes are an id that specifies the sync request. It is
-represented by four utf-8 characters. The last four bytes are a Little-Endian
-integer, with various uses. This number will be called "length" below. In fact
-all binary integers are Little-Endian in the sync mode. Sync mode is
-implicitly exited after each sync request, and normal adb communication
-follows as described in SERVICES.TXT.
-
-The following sync requests are accepted:
-LIST - List the files in a folder
-RECV - Retrieve a file from device
-SEND - Send a file to device
-STAT - Stat a file
-
-All of the sync requests above must be followed by "length": the number of
-bytes containing a utf-8 string with a remote filename.
-
-LIST:
-Lists files in the directory specified by the remote filename. The server will
-respond with zero or more directory entries or "dents".
-
-The directory entries will be returned in the following form
-1. A four-byte sync response id "DENT"
-2. A four-byte integer representing file mode.
-3. A four-byte integer representing file size.
-4. A four-byte integer representing last modified time.
-5. A four-byte integer representing file name length.
-6. length number of bytes containing an utf-8 string representing the file
-   name.
-
-When a sync response "DONE" is received the listing is done.
-
-SEND:
-The remote file name is split into two parts separated by the last
-comma (","). The first part is the actual path, while the second is a decimal
-encoded file mode containing the permissions of the file on device.
-
-Note that some file types will be deleted before the copying starts, and if
-the transfer fails. Some file types will not be deleted, which allows
-  adb push disk_image /some_block_device
-to work.
-
-After this the actual file is sent in chunks. Each chunk has the following
-format.
-A sync request with id "DATA" and length equal to the chunk size. After
-follows chunk size number of bytes. This is repeated until the file is
-transferred. Each chunk must not be larger than 64k.
-
-When the file is transferred a sync request "DONE" is sent, where length is set
-to the last modified time for the file. The server responds to this last
-request (but not to chunk requests) with an "OKAY" sync response (length can
-be ignored).
-
-
-RECV:
-Retrieves a file from device to a local file. The remote path is the path to
-the file that will be returned. Just as for the SEND sync request the file
-received is split up into chunks. The sync response id is "DATA" and length is
-the chunk size. After follows chunk size number of bytes. This is repeated
-until the file is transferred. Each chunk will not be larger than 64k.
-
-When the file is transferred a sync response "DONE" is retrieved where the
-length can be ignored.

-  //   components.

-/* here's how these things work.
-
-   when adbd starts, it creates a unix server socket
-   named @jdwp-control (@ is a shortcut for "first byte is zero"
-   to use the private namespace instead of the file system)
-
-   when a new JDWP daemon thread starts in a new VM process, it creates
-   a connection to @jdwp-control to announce its availability.
-
-
-     JDWP thread                             @jdwp-control
-         |                                         |
-         |------------------------------->         |
-         | hello I'm in process <pid>              |
-         |                                         |
-         |                                         |
-
-    the connection is kept alive. it will be closed automatically if
-    the JDWP process terminates (this allows adbd to detect dead
-    processes).
-
-    adbd thus maintains a list of "active" JDWP processes. it can send
-    its content to clients through the "device:debug-ports" service,
-    or even updates through the "device:track-debug-ports" service.
-
-    when a debugger wants to connect, it simply runs the command
-    equivalent to  "adb forward tcp:<hostport> jdwp:<pid>"
-
-    "jdwp:<pid>" is a new forward destination format used to target
-    a given JDWP process on the device. when sutch a request arrives,
-    adbd does the following:
-
-      - first, it calls socketpair() to create a pair of equivalent
-        sockets.
-
-      - it attaches the first socket in the pair to a local socket
-        which is itself attached to the transport's remote socket:
-
-
-      - it sends the file descriptor of the second socket directly
-        to the JDWP process with the help of sendmsg()
-
-
-     JDWP thread                             @jdwp-control
-         |                                         |
-         |                  <----------------------|
-         |           OK, try this file descriptor  |
-         |                                         |
-         |                                         |
-
-   then, the JDWP thread uses this new socket descriptor as its
-   pass-through connection to the debugger (and receives the
-   JDWP-Handshake message, answers to it, etc...)
-
-   this gives the following graphics:

-
-    due to the way adb works, this doesn't need a special socket
-    type or fancy handling of socket termination if either the debugger
-    or the JDWP process closes the connection.

-    THIS IS THE SIMPLEST IMPLEMENTATION I COULD FIND, IF YOU HAPPEN
-    TO HAVE A BETTER IDEA, LET ME KNOW - Digit

-// Functionality for launching and managing shell subprocesses.
-//
-// There are two types of subprocesses, PTY or raw. PTY is typically used for
-// an interactive session, raw for non-interactive. There are also two methods
-// of communication with the subprocess, passing raw data or using a simple
-// protocol to wrap packets. The protocol allows separating stdout/stderr and
-// passing the exit code back, but is not backwards compatible.
-//   ----------------+--------------------------------------
-//   Type  Protocol  |   Exit code?  Separate stdout/stderr?
-//   ----------------+--------------------------------------
-//   PTY   No        |   No          No
-//   Raw   No        |   No          No
-//   PTY   Yes       |   Yes         No
-//   Raw   Yes       |   Yes         Yes
-//   ----------------+--------------------------------------
-//
-// Non-protocol subprocesses work by passing subprocess stdin/out/err through
-// a single pipe which is registered with a local socket in adbd. The local
-// socket uses the fdevent loop to pass raw data between this pipe and the
-// transport, which then passes data back to the adb client. Cleanup is done by
-// waiting in a separate thread for the subprocesses to exit and then signaling
-// a separate fdevent to close out the local socket from the main loop.
-//
-// ------------------+-------------------------+------------------------------
-//   Subprocess      |  adbd subprocess thread |   adbd main fdevent loop
-// ------------------+-------------------------+------------------------------
-//                   |                         |
-//   stdin/out/err <----------------------------->       LocalSocket
-//      |            |                         |
-//      |            |      Block on exit      |
-//      |            |           *             |
-//      v            |           *             |
-//     Exit         --->      Unblock          |
-//                   |           |             |
-//                   |           v             |
-//                   |   Notify shell exit FD --->    Close LocalSocket
-// ------------------+-------------------------+------------------------------
-//
-// The protocol requires the thread to intercept stdin/out/err in order to
-// wrap/unwrap data with shell protocol packets.
-//
-// ------------------+-------------------------+------------------------------
-//   Subprocess      |  adbd subprocess thread |   adbd main fdevent loop
-// ------------------+-------------------------+------------------------------
-//                   |                         |
-//     stdin/out   <--->      Protocol       <--->       LocalSocket
-//     stderr       --->      Protocol        --->       LocalSocket
-//       |           |                         |
-//       v           |                         |
-//      Exit        --->  Exit code protocol  --->       LocalSocket
-//                   |           |             |
-//                   |           v             |
-//                   |   Notify shell exit FD --->    Close LocalSocket
-// ------------------+-------------------------+------------------------------
-//
-// An alternate approach is to put the protocol wrapping/unwrapping in the main
-// fdevent loop, which has the advantage of being able to re-use the existing
-// select() code for handling data streams. However, implementation turned out
-// to be more complex due to partial reads and non-blocking I/O so this model
-// was chosen instead.

-/* A worker thread that monitors host connections, and registers a transport for
- * every new host connection. This thread replaces server_socket_thread on
- * condition that adbd daemon runs inside the emulator, and emulator uses QEMUD
- * pipe to communicate with adbd daemon inside the guest. This is done in order
- * to provide more robust communication channel between ADB host and guest. The
- * main issue with server_socket_thread approach is that it runs on top of TCP,
- * and thus is sensitive to network disruptions. For instance, the
- * ConnectionManager may decide to reset all network connections, in which case
- * the connection between ADB host and guest will be lost. To make ADB traffic
- * independent from the network, we use here 'adb' QEMUD service to transfer data
- * between the host, and the guest. See external/qemu/android/adb-*.* that
- * implements the emulator's side of the protocol. Another advantage of using
- * QEMUD approach is that ADB will be up much sooner, since it doesn't depend
- * anymore on network being set up.
- * The guest side of the protocol contains the following phases:
- * - Connect with adb QEMUD service. In this phase a handle to 'adb' QEMUD service
- *   is opened, and it becomes clear whether or not emulator supports that
- *   protocol.
- * - Wait for the ADB host to create connection with the guest. This is done by
- *   sending an 'accept' request to the adb QEMUD service, and waiting on
- *   response.
- * - When new ADB host connection is accepted, the connection with adb QEMUD
- *   service is registered as the transport, and a 'start' request is sent to the
- *   adb QEMUD service, indicating that the guest is ready to receive messages.
- *   Note that the guest will ignore messages sent down from the emulator before
- *   the transport registration is completed. That's why we need to send the
- *   'start' request after the transport is registered.

-
---- a replacement for aproto -------------------------------------------
-
-When it comes down to it, aproto's primary purpose is to forward
-various streams between the host computer and client device (in either
-direction).
-
-This replacement further simplifies the concept, reducing the protocol
-to an extremely straightforward model optimized to accomplish the
-forwarding of these streams and removing additional state or
-complexity.
-
-The host side becomes a simple comms bridge with no "UI", which will 
-be used by either commandline or interactive tools to communicate with 
-a device or emulator that is connected to the bridge.
-
-The protocol is designed to be straightforward and well-defined enough 
-that if it needs to be reimplemented in another environment (Java 
-perhaps), there should not problems ensuring perfect interoperability.
-
-The protocol discards the layering aproto has and should allow the 
-implementation to be much more robust.
-
-
---- protocol overview and basics ---------------------------------------
-
-The transport layer deals in "messages", which consist of a 24 byte
-header followed (optionally) by a payload.  The header consists of 6
-32 bit words which are sent across the wire in little endian format.
-
-struct message {
-    unsigned command;       /* command identifier constant (A_CNXN, ...) */
-    unsigned arg0;          /* first argument                            */
-    unsigned arg1;          /* second argument                           */
-    unsigned data_length;   /* length of payload (0 is allowed)          */
-    unsigned data_crc32;    /* crc32 of data payload                     */
-    unsigned magic;         /* command ^ 0xffffffff                      */
-};
-
-Receipt of an invalid message header, corrupt message payload, or an
-unrecognized command MUST result in the closing of the remote
-connection.  The protocol depends on shared state and any break in the
-message stream will result in state getting out of sync.
-
-The following sections describe the six defined message types in
-detail.  Their format is COMMAND(arg0, arg1, payload) where the payload
-is represented by a quoted string or an empty string if none should be
-sent.
-
-The identifiers "local-id" and "remote-id" are always relative to the
-*sender* of the message, so for a receiver, the meanings are effectively
-reversed.
-
-
-
---- CONNECT(version, maxdata, "system-identity-string") ----------------
-
-Command constant: A_CNXN
-
-The CONNECT message establishes the presence of a remote system.
-The version is used to ensure protocol compatibility and maxdata
-declares the maximum message body size that the remote system
-is willing to accept.
-
-Currently, version=0x01000000 and maxdata=256*1024. Older versions of adb
-hard-coded maxdata=4096, so CONNECT and AUTH packets sent to a device must not
-be larger than that because they're sent before the CONNECT from the device
-that tells the adb server what maxdata the device can support.
-
-Both sides send a CONNECT message when the connection between them is
-established.  Until a CONNECT message is received no other messages may
-be sent. Any messages received before a CONNECT message MUST be ignored.
-
-If a CONNECT message is received with an unknown version or insufficiently
-large maxdata value, the connection with the other side must be closed.
-
-The system identity string should be "<systemtype>:<serialno>:<banner>"
-where systemtype is "bootloader", "device", or "host", serialno is some
-kind of unique ID (or empty), and banner is a human-readable version
-or identifier string.  The banner is used to transmit useful properties.
-
---- STLS(type, version, "") --------------------------------------------
-
-Command constant: A_STLS
-
-The TLS message informs the recipient that the connection will be encrypted
-and will need to perform a TLS handshake. version is the current version of
-the protocol.
-
-
---- AUTH(type, 0, "data") ----------------------------------------------
-
-Command constant: A_AUTH
-
-The AUTH message informs the recipient that authentication is required to
-connect to the sender. If type is TOKEN(1), data is a random token that
-the recipient can sign with a private key. The recipient replies with an
-AUTH packet where type is SIGNATURE(2) and data is the signature. If the
-signature verification succeeds, the sender replies with a CONNECT packet.
-
-If the signature verification fails, the sender replies with a new AUTH
-packet and a new random token, so that the recipient can retry signing
-with a different private key.
-
-Once the recipient has tried all its private keys, it can reply with an
-AUTH packet where type is RSAPUBLICKEY(3) and data is the public key. If
-possible, an on-screen confirmation may be displayed for the user to
-confirm they want to install the public key on the device.
-
-
---- OPEN(local-id, 0, "destination") -----------------------------------
-
-Command constant: A_OPEN
-
-The OPEN message informs the recipient that the sender has a stream
-identified by local-id that it wishes to connect to the named
-destination in the message payload.  The local-id may not be zero.
-
-The OPEN message MUST result in either a READY message indicating that
-the connection has been established (and identifying the other end) or
-a CLOSE message, indicating failure.  An OPEN message also implies
-a READY message sent at the same time.
-
-Common destination naming conventions include:
-
-* "tcp:<host>:<port>" - host may be omitted to indicate localhost
-* "udp:<host>:<port>" - host may be omitted to indicate localhost
-* "local-dgram:<identifier>"
-* "local-stream:<identifier>"
-* "shell" - local shell service
-* "upload" - service for pushing files across (like aproto's /sync)
-* "fs-bridge" - FUSE protocol filesystem bridge
-
-
---- READY(local-id, remote-id, "") -------------------------------------
-
-Command constant: A_OKAY
-
-The READY message informs the recipient that the sender's stream
-identified by local-id is ready for write messages and that it is
-connected to the recipient's stream identified by remote-id.
-
-Neither the local-id nor the remote-id may be zero.
-
-A READY message containing a remote-id which does not map to an open
-stream on the recipient's side is ignored.  The stream may have been
-closed while this message was in-flight.
-
-The local-id is ignored on all but the first READY message (where it
-is used to establish the connection).  Nonetheless, the local-id MUST
-not change on later READY messages sent to the same stream.
-
-
---- WRITE(local-id, remote-id, "data") ---------------------------------
-
-Command constant: A_WRTE
-
-The WRITE message sends data to the recipient's stream identified by
-remote-id.  The payload MUST be <= maxdata in length.
-
-A WRITE message containing a remote-id which does not map to an open
-stream on the recipient's side is ignored.  The stream may have been
-closed while this message was in-flight.
-
-A WRITE message may not be sent until a READY message is received.
-Once a WRITE message is sent, an additional WRITE message may not be
-sent until another READY message has been received.  Recipients of
-a WRITE message that is in violation of this requirement will CLOSE
-the connection.
-
-
---- CLOSE(local-id, remote-id, "") -------------------------------------
-
-Command constant: A_CLSE
-
-The CLOSE message informs recipient that the connection between the
-sender's stream (local-id) and the recipient's stream (remote-id) is
-broken.  The remote-id MUST not be zero, but the local-id MAY be zero
-if this CLOSE indicates a failed OPEN.
-
-A CLOSE message containing a remote-id which does not map to an open
-stream on the recipient's side is ignored.  The stream may have
-already been closed by the recipient while this message was in-flight.
-
-The recipient should not respond to a CLOSE message in any way.  The
-recipient should cancel pending WRITEs or CLOSEs, but this is not a
-requirement, since they will be ignored.
-
-
---- SYNC(online, sequence, "") -----------------------------------------
-
-Command constant: A_SYNC
-
-*** obsolete, no longer used ***
-
-The SYNC message was used by the io pump to make sure that stale
-outbound messages are discarded when the connection to the remote side
-is broken.  It was only used internally to the bridge and never valid
-to send across the wire.
-
-* when the connection to the remote side goes offline, the io pump
-  sends a SYNC(0, 0) and starts discarding all messages
-* when the connection to the remote side is established, the io pump
-  sends a SYNC(1, token) and continues to discard messages
-* when the io pump receives a matching SYNC(1, token), it once again
-  starts accepting messages to forward to the remote side
-
-
---- message command constants ------------------------------------------
-
-#define A_SYNC 0x434e5953
-#define A_CNXN 0x4e584e43
-#define A_AUTH 0x48545541
-#define A_OPEN 0x4e45504f

-#define A_CLSE 0x45534c43
-#define A_WRTE 0x45545257
-#define A_STLS 0x534C5453
-
-
-
---- implementation details ---------------------------------------------
-
-The core of the bridge program will use three threads.  One thread
-will be a select/epoll loop to handle io between various inbound and
-outbound connections and the connection to the remote side.
-
-The remote side connection will be implemented as two threads (one for
-reading, one for writing) and a datagram socketpair to provide the
-channel between the main select/epoll thread and the remote connection
-threadpair.  The reason for this is that for usb connections, the
-kernel interface on linux and osx does not allow you to do meaningful
-nonblocking IO.
-
-The endian swapping for the message headers will happen (as needed) in
-the remote connection threadpair and that the rest of the program will
-always treat message header values as native-endian.
-
-The bridge program will be able to have a number of mini-servers
-compiled in.  They will be published under known names (examples
-"shell", "fs-bridge", etc) and upon receiving an OPEN() to such a
-service, the bridge program will create a stream socketpair and spawn
-a thread or subprocess to handle the io.
-
-
---- simplified / embedded implementation -------------------------------
-
-For limited environments, like the bootloader, it is allowable to
-support a smaller, fixed number of channels using pre-assigned channel
-ID numbers such that only one stream may be connected to a bootloader
-endpoint at any given time.  The protocol remains unchanged, but the
-"embedded" version of it is less dynamic.
-
-The bootloader will support two streams.  A "bootloader:debug" stream,
-which may be opened to get debug messages from the bootloader and a 
-"bootloader:control", stream which will support the set of basic 
-bootloader commands.
-
-Example command stream dialogues:  
-  "flash_kernel,2515049,........\n" "okay\n" 
-  "flash_ramdisk,5038,........\n" "fail,flash write error\n" 
-  "bogus_command......" <CLOSE>
-
-
---- future expansion ---------------------------------------------------
-
-I plan on providing either a message or a special control stream so that
-the client device could ask the host computer to setup inbound socket
-translations on the fly on behalf of the client device.
-
-
-The initial design does handshaking to provide flow control, with a
-message flow that looks like:
-
-  >OPEN <READY >WRITE <READY >WRITE <READY >WRITE <CLOSE
-
-The far side may choose to issue the READY message as soon as it receives
-a WRITE or it may defer the READY until the write to the local stream
-succeeds.  A future version may want to do some level of windowing where
-multiple WRITEs may be sent without requiring individual READY acks.
-
-------------------------------------------------------------------------
-
---- smartsockets -------------------------------------------------------
-
-Port 5037 is used for smart sockets which allow a client on the host
-side to request access to a service in the host adb daemon or in the
-remote (device) daemon.  The service is requested by ascii name,
-preceeded by a 4 digit hex length.  Upon successful connection an
-"OKAY" response is sent, otherwise a "FAIL" message is returned.  Once
-connected the client is talking to that (remote or local) service.
-
-client: <hex4> <service-name>
-server: "OKAY"
-
-client: <hex4> <service-name>
-server: "FAIL" <hex4> <reason>

-// This reads input from a Win32 console window and translates it into Unix

-// is emulated instead of xterm because it is probably more popular than xterm:
-// Ubuntu's default Ctrl-Alt-T shortcut opens Gnome Terminal, Gnome Terminal
-// supports modern fonts, etc. It seems best to emulate the terminal that most
-// Android developers use because they'll fix apps (the shell, etc.) to keep
-// working with that terminal's emulation.
-//
-// The point of this emulation is not to be perfect or to solve all issues with

-// just called read() (which called ReadFile(), which called ReadConsoleA())
-// which did not support Ctrl-C, tab completion, shell input line editing
-// keys, server echo, and more.
-//
-// This implementation reconfigures the console with SetConsoleMode(), then
-// calls ReadConsoleInput() to get raw input which it remaps to Unix
-// terminal-style sequences which is returned via unix_read() which is used
-// by the 'adb shell' command.
-//
-// Code organization:
-//
-// * _get_console_handle() and unix_isatty() provide console information.
-// * stdin_raw_init() and stdin_raw_restore() reconfigure the console.
-// * unix_read() detects console windows (as opposed to pipes, files, etc.).
-// * _console_read() is the main code of the emulation.

-
-// This implements support for using files with Unicode filenames and for
-// outputting Unicode text to a Win32 console window. This is inspired from
-// http://utf8everywhere.org/.
-//
-// Background
-// ----------
-//
-// On POSIX systems, to deal with files with Unicode filenames, just pass UTF-8
-// filenames to APIs such as open(). This works because filenames are largely
-// opaque 'cookies' (perhaps excluding path separators).
-//
-// On Windows, the native file APIs such as CreateFileW() take 2-byte wchar_t
-// UTF-16 strings. There is an API, CreateFileA() that takes 1-byte char
-// strings, but the strings are in the ANSI codepage and not UTF-8. (The
-// CreateFile() API is really just a macro that adds the W/A based on whether
-// the UNICODE preprocessor symbol is defined).
-//
-// Options
-// -------
-//
-// Thus, to write a portable program, there are a few options:
-//
-// 1. Write the program with wchar_t filenames (wchar_t path[256];).
-//    For Windows, just call CreateFileW(). For POSIX, write a wrapper openW()
-//    that takes a wchar_t string, converts it to UTF-8 and then calls the real
-//    open() API.
-//
-// 2. Write the program with a TCHAR typedef that is 2 bytes on Windows and
-//    1 byte on POSIX. Make T-* wrappers for various OS APIs and call those,
-//    potentially touching a lot of code.
-//
-// 3. Write the program with a 1-byte char filenames (char path[256];) that are
-//    UTF-8. For POSIX, just call open(). For Windows, write a wrapper that
-//    takes a UTF-8 string, converts it to UTF-16 and then calls the real OS
-//    or C Runtime API.
-//
-// The Choice
-// ----------
-//
-// The code below chooses option 3, the UTF-8 everywhere strategy. It uses
-// android::base::WideToUTF8() which converts UTF-16 to UTF-8. This is used by the
-// NarrowArgs helper class that is used to convert wmain() args into UTF-8
-// args that are passed to main() at the beginning of program startup. We also use
-// android::base::UTF8ToWide() which converts from UTF-8 to UTF-16. This is used to
-// implement wrappers below that call UTF-16 OS and C Runtime APIs.
-//
-// Unicode console output
-// ----------------------
-//
-// The way to output Unicode to a Win32 console window is to call
-// WriteConsoleW() with UTF-16 text. (The user must also choose a proper font
-// such as Lucida Console or Consolas, and in the case of East Asian languages
-// (such as Chinese, Japanese, Korean), the user must go to the Control Panel
-// and change the "system locale" to Chinese, etc., which allows a Chinese, etc.
-// font to be used in console windows.)
-//
-// The problem is getting the C Runtime to make fprintf and related APIs call
-// WriteConsoleW() under the covers. The C Runtime API, _setmode() sounds
-// promising, but the various modes have issues:
-//
-// 1. _setmode(_O_TEXT) (the default) does not use WriteConsoleW() so UTF-8 and
-//    UTF-16 do not display properly.
-// 2. _setmode(_O_BINARY) does not use WriteConsoleW() and the text comes out
-//    totally wrong.
-// 3. _setmode(_O_U8TEXT) seems to cause the C Runtime _invalid_parameter
-//    handler to be called (upon a later I/O call), aborting the process.
-// 4. _setmode(_O_U16TEXT) and _setmode(_O_WTEXT) cause non-wide printf/fprintf
-//    to output nothing.
-//
-// So the only solution is to write our own adb_fprintf() that converts UTF-8
-// to UTF-16 and then calls WriteConsoleW().

-// be passed to main().

+ * 4: We need to assign new_chunk for a corresponding old_chunk
+ * 5: The algorithm is similar to how kernel assigns chunk number
+ *    while creating exceptions.
+ * 6: Use a monotonically increasing chunk number to assign the
+ *    new_chunk
+ * 7: Each chunk-id represents either a: Metadata page or b: Data page
+ * 8: Chunk-id representing a data page is stored in a vector. Index is the
+ *    chunk-id and value is the pointer to the CowOperation
+ * 9: Chunk-id representing a metadata page is converted into a vector
+ *    index. We store this in vector as kernel requests metadata during

+ *       a: When initial dm-snapshot device is created, kernel requests
+ *          all the metadata and stores it in its internal data-structures.
+ *       b: During merge, kernel once again requests the same metadata
+ *          once-again.
+ *    In both these cases, a quick lookup based on chunk-id is done.
+ * 10: When chunk number is incremented, we need to make sure that
+ *    if the chunk is representing a metadata page and skip.
+ * 11: Each 4k page will contain 256 disk exceptions. We call this
+ *    exceptions_per_area_
+ * 12: Kernel will stop issuing metadata IO request when new-chunk ID is 0.

+ * However, client library will mark the first stage daemon as passive and hence

+ * daemon.
+ *
+ * 5: Create new dm-snapshot table. This is done by libsnapshot. When new table

+ *
+ * 7: Stop the first stage daemon. After this point second stage daemon is

-Description
------------
-
-liblog represents an interface to the volatile Android Logging system for NDK (Native) applications
-and libraries.  Interfaces for either writing or reading logs.  The log buffers are divided up in
-Main, System, Radio and Events sub-logs.
-
-The logging interfaces are a series of macros, all of which can be overridden individually in order
-to control the verbosity of the application or library.  `[ASR]LOG[VDIWE]` calls are used to log to
-BAsic, System or Radio sub-logs in either the Verbose, Debug, Info, Warning or Error priorities.
-`[ASR]LOG[VDIWE]_IF` calls are used to perform thus based on a condition being true.
-`IF_ALOG[VDIWE]` calls are true if the current `LOG_TAG` is enabled at the specified priority.
-`LOG_ALWAYS_FATAL` is used to `ALOG` a message, then kill the process.  `LOG_FATAL` call is a
-variant of `LOG_ALWAYS_FATAL`, only enabled in engineering, and not release builds.  `ALOG_ASSERT`
-is used to `ALOG` a message if the condition is false; the condition is part of the logged message.
-`LOG_EVENT_(INT|LONG)` is used to drop binary content into the Events sub-log.
-
-The log reading interfaces permit opening the logs either singly or multiply, retrieving a log entry
-at a time in time sorted order, optionally limited to a specific pid and tail of the log(s) and
-finally a call closing the logs.  A single log can be opened with `android_logger_list_open()`; or
-multiple logs can be opened with `android_logger_list_alloc()`, calling in turn the
-`android_logger_open()` for each log id.  Each entry can be retrieved with
-`android_logger_list_read()`.  The log(s) can be closed with `android_logger_list_free()`.
-`ANDROID_LOG_NONBLOCK` mode will report when the log reading is done with an `EAGAIN` error return
-code, otherwise the `android_logger_list_read()` call will block for new entries.
-
-The `ANDROID_LOG_WRAP` mode flag to the `android_logger_list_alloc_time()` signals logd to quiesce
-the reader until the buffer is about to prune at the start time then proceed to dumping content.
-
-The `ANDROID_LOG_PSTORE` mode flag to the `android_logger_open()` is used to switch from the active
-logs to the persistent logs from before the last reboot.
-
-The value returned by `android_logger_open()` can be used as a parameter to the
-`android_logger_clear()` function to empty the sub-log.
-
-The value returned by `android_logger_open()` can be used as a parameter to the
-`android_logger_get_log_(size|readable_size|version)` to retrieve the sub-log maximum size, readable
-size and log buffer format protocol version respectively.  `android_logger_get_id()` returns the id
-that was used when opening the sub-log.
-
-Errors
-------
-
-If messages fail, a negative error code will be returned to the caller.
-
-The `-ENOTCONN` return code indicates that the logger daemon is stopped.
-
-The `-EBADF` return code indicates that the log access point can not be opened, or the log buffer id
-is out of range.
-
-For the `-EAGAIN` return code, this means that the logging message was temporarily backed-up either
-because of Denial Of Service (DOS) logging pressure from some chatty application or service in the
-Android system, or if too small of a value is set in /proc/sys/net/unix/max_dgram_qlen.  To aid in
-diagnosing the occurence of this, a binary event from liblog will be sent to the log daemon once a
-new message can get through indicating how many messages were dropped as a result.  Please take
-action to resolve the structural problems at the source.
-
-It is generally not advised for the caller to retry the `-EAGAIN` return code as this will only make
-the problem(s) worse and cause your application to temporarily drop to the logger daemon priority,
-BATCH scheduling policy and background task cgroup. If you require a group of messages to be passed
-atomically, merge them into one message with embedded newlines to the maximum length
-`LOGGER_ENTRY_MAX_PAYLOAD`.
-
-Other return codes from writing operation can be returned.  Since the library retries on `EINTR`,
-`-EINTR` should never be returned.

-        int32_t length;
-        char data[];
-    };
-
-The payload, excluding the header, has a max size of LOGGER_ENTRY_MAX_PAYLOAD.
-
-## header
-
-The header is added immediately before sending the log message to logd.
-
-## `string` payload
-
-The `string` part of the union is for normal buffers (main, system, radio, etc) and consists of a
-single character priority, followed by a variable length null terminated string for the tag, and
-finally a variable length null terminated string for the message.
-
-This payload is used for the `__android_log_buf_write()` family of functions.
-
-## `binary` payload
-
-The `binary` part of the union is for binary buffers (events, security, etc) and consists of an
-android_event_header_t struct followed by a variable number of android_event_*_t
-(android_event_list_t, android_event_int_t, etc) structs.
-
-If multiple android_event_*_t elements are present, then they must be in a list and the first
-element in payload must be an android_event_list_t.
-
-This payload is used for the `__android_log_bwrite()` family of functions. It is additionally used
-for `android_log_write_list()` and the related functions that manipulate event lists.
-
-# logd -> liblog
-
-logd sends a `logger_entry` struct to liblog followed by the payload. The payload is identical to
-the payloads defined above. The max size of the entire message from logd is LOGGER_ENTRY_MAX_LEN.

- *  - Sending log messages eats CPU and slow down your application and the

- *
- *  - The circular log buffer is pretty small, so sending many messages

-I learn in this letter that Don Peter of Arragon\n\
-comes this night to Messina\n\
-MESSENGER\n\
-He is very near by this: he was not three leagues off\n\
-when I left him\n\
-LEONATO\n\
-How many gentlemen have you lost in this action?\n\
-MESSENGER\n\
-But few of any sort, and none of name\n\
-LEONATO\n\
-A victory is twice itself when the achiever brings\n\
-home full numbers. I find here that Don Peter hath\n\
-bestowed much honour on a young Florentine called Claudio\n\
-MESSENGER\n\
-Much deserved on his part and equally remembered by\n\
-Don Pedro: he hath borne himself beyond the\n\
-promise of his age, doing, in the figure of a lamb,\n\
-the feats of a lion: he hath indeed better\n\
-bettered expectation than you must expect of me to\n\
-tell you how\n\
-LEONATO\n\
-He hath an uncle here in Messina will be very much\n\
-glad of it.\n\
-MESSENGER\n\
-I have already delivered him letters, and there\n\
-appears much joy in him; even so much that joy could\n\
-not show itself modest enough without a badge of\n\
-bitterness.\n\
-LEONATO\n\
-Did he break out into tears?\n\
-MESSENGER\n\
-In great measure.\n\
-LEONATO\n\
-A kind overflow of kindness: there are no faces\n\
-truer than those that are so washed. How much\n\
-better is it to weep at joy than to joy at weeping!\n\
-BEATRICE\n\
-I pray you, is Signior Mountanto returned from the\n\
-wars or no?\n\
-MESSENGER\n\
-I know none of that name, lady: there was none such\n\
-in the army of any sort.\n\
-LEONATO\n\
-What is he that you ask for, niece?\n\
-HERO\n\
-My cousin means Signior Benedick of Padua.\n\
-MESSENGER\n\
-O, he's returned; and as pleasant as ever he was.\n\
-BEATRICE\n\
-He set up his bills here in Messina and challenged\n\
-Cupid at the flight; and my uncle's fool, reading\n\
-the challenge, subscribed for Cupid, and challenged\n\
-him at the bird-bolt. I pray you, how many hath he\n\
-killed and eaten in these wars? But how many hath\n\
-he killed? for indeed I promised to eat all of his killing.\n\
-LEONATO\n\
-Faith, niece, you tax Signior Benedick too much;\n\
-but he'll be meet with you, I doubt it not.\n\
-MESSENGER\n\
-He hath done good service, lady, in these wars.\n\
-BEATRICE\n\
-You had musty victual, and he hath holp to eat it:\n\
-he is a very valiant trencherman; he hath an\n\
-excellent stomach.\n\
-MESSENGER\n\
-And a good soldier too, lady.\n\
-BEATRICE\n\
-And a good soldier to a lady: but what is he to a lord?\n\
-MESSENGER\n\
-A lord to a lord, a man to a man; stuffed with all\n\
-honourable virtues.\n\
-BEATRICE\n\
-It is so, indeed; he is no less than a stuffed man:\n\
-but for the stuffing,--well, we are all mortal.\n\
-LEONATO\n\
-You must not, sir, mistake my niece. There is a\n\
-kind of merry war betwixt Signior Benedick and her:\n\
-they never meet but there's a skirmish of wit\n\
-between them.\n\
-BEATRICE\n\
-Alas! he gets nothing by that. In our last\n\
-conflict four of his five wits went halting off, and\n\
-now is the whole man governed with one: so that if\n\
-he have wit enough to keep himself warm, let him\n\
-bear it for a difference between himself and his\n\
-horse; for it is all the wealth that he hath left,\n\
-to be known a reasonable creature. Who is his\n\
-companion now? He hath every month a new sworn brother.\n\
-MESSENGER\n\
-Is't possible?\n\
-BEATRICE\n\
-Very easily possible: he wears his faith but as\n\
-the fashion of his hat; it ever changes with the\n\
-next block.\n\
-MESSENGER\n\
-I see, lady, the gentleman is not in your books.\n\
-BEATRICE\n\
-No; an he were, I would burn my study. But, I pray\n\
-you, who is his companion? Is there no young\n\
-squarer now that will make a voyage with him to the devil?\n\
-MESSENGER\n\
-He is most in the company of the right noble Claudio.\n\
-BEATRICE\n\
-O Lord, he will hang upon him like a disease: he\n\
-is sooner caught than the pestilence, and the taker\n\
-runs presently mad. God help the noble Claudio! if\n\
-he have caught the Benedick, it will cost him a\n\
-thousand pound ere a' be cured.\n\
-MESSENGER\n\
-I will hold friends with you, lady.\n\
-BEATRICE\n\
-Do, good friend.\n\
-LEONATO\n\
-You will never run mad, niece.\n\
-BEATRICE\n\
-No, not till a hot January.\n\
-MESSENGER\n\
-Don Pedro is approached.\n\
-Enter DON PEDRO, DON JOHN, CLAUDIO, BENEDICK, and BALTHASAR\n\
-\n\
-DON PEDRO\n\
-Good Signior Leonato, you are come to meet your\n\
-trouble: the fashion of the world is to avoid\n\
-cost, and you encounter it\n\
-LEONATO\n\
-Never came trouble to my house in the likeness of your grace,\n\
-for trouble being gone, comfort should remain, but\n\
-when you depart from me, sorrow abides and happiness\n\
-takes his leave.";

-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,

-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and

-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-** - Translates each ArmAssemblerInterface call to generate
-**   one or more Arm64 instructions  as necessary.
-**
-** - Does not implement ArmAssemblerInterface portions unused by GGLAssembler
-**   It calls NOT_IMPLEMENTED() for such cases, which in turn logs
-**    a fatal message.
-**
-** - Uses A64_.. series of functions to generate instruction machine code
-**   for Arm64 instructions. These functions also log the instruction
-**   to LOG, if ARM64_ASM_DEBUG define is set to 1
-**
-** - Dumps machine code and eqvt assembly if "debug.pf.disasm" option is set
-**   It uses arm64_disassemble to perform disassembly
-**
-** - Uses register 13 (SP in ARM), 15 (PC in ARM), 16, 17 for storing
-**   intermediate results. GGLAssembler does not use SP and PC as these
-**   registers are marked as reserved. The temporary registers are not
-**   saved/restored on stack as these are caller-saved registers in Arm64
-**
-** - Uses CSEL instruction to support conditional execution. The result is
-**   stored in a temporary register and then copied to the target register
-**   if the condition is true.
-**
-** - In the case of conditional data transfer instructions, conditional
-**   branch is used to skip over instruction, if the condition is false
-**
-** - Wherever possible, immediate values are transferred to temporary
-**   register prior to processing. This simplifies overall implementation
-**   as instructions requiring immediate values are converted to
-**   move immediate instructions followed by register-register instruction.
-**
-** --------------------------------------------
-** ArmToArm64Assembler unit test bench
-** --------------------------------------------
-**
-** - Tests ArmToArm64Assembler interface for all the possible
-**   ways in which GGLAssembler uses ArmAssemblerInterface interface.
-**
-** - Uses test jacket (written in assembly) to set the registers,
-**   condition flags prior to calling generated instruction. It also
-**   copies registers and flags at the end of execution. Caller then
-**   checks if generated code performed correct operation based on
-**   output registers and flags.
-**
-** - Broadly contains three type of tests, (i) data operation tests
-**   (ii) data transfer tests and (iii) LDM/STM tests.
-**
-** ----------------------
-** Arm64 disassembler
-** ----------------------
-** - This disassembler disassembles only those machine codes which can be
-**   generated by ArmToArm64Assembler. It has a unit testbench which
-**   tests all the instructions supported by the disassembler.
-**
-** ------------------------------------------------------------------
-** ARMAssembler/ARMAssemblerInterface/ARMAssemblerProxy changes
-** ------------------------------------------------------------------
-**
-** - In existing code, addresses were being handled as 32 bit values at
-**   certain places.
-**
-** - Added a new set of functions for address load/store/manipulation.
-**   These are ADDR_LDR, ADDR_STR, ADDR_ADD, ADDR_SUB and they map to
-**   default 32 bit implementations in ARMAssemblerInterface.
-**
-** - ArmToArm64Assembler maps these functions to appropriate 64 bit
-**   functions.
-**
-** ----------------------
-** GGLAssembler changes
-** ----------------------
-** - Since ArmToArm64Assembler can generate 4 Arm64 instructions for
-**   each call in worst case, the memory required is set to 4 times
-**   ARM memory
-**
-** - Address load/store/manipulation were changed to use new functions
-**   added in the ARMAssemblerInterface.

-/* MIPS assembler and ARM->MIPS assembly translator
-**
-** The approach is to leave the GGLAssembler and associated files largely
-** un-changed, still utilizing all Arm instruction generation. Via the
-** ArmToMipsAssembler (subclassed from ArmAssemblerInterface) each Arm
-** instruction is translated to one or more Mips instructions as necessary. This
-** is clearly less efficient than a direct implementation within the
-** GGLAssembler, but is far cleaner, more maintainable, and has yielded very
-** significant performance gains on Mips compared to the generic pixel pipeline.
-**
-**
-** GGLAssembler changes
-**
-** - The register allocator has been modified to re-map Arm registers 0-15 to mips
-** registers 2-17. Mips register 0 cannot be used as general-purpose register,
-** and register 1 has traditional uses as a short-term temporary.
-**
-** - Added some early bailouts for OUT_OF_REGISTERS in texturing.cpp and
-** GGLAssembler.cpp, since this is not fatal, and can be retried at lower
-** optimization level.
-**
-**
-** ARMAssembler and ARMAssemblerInterface changes
-**
-** Refactored ARM address-mode static functions (imm(), reg_imm(), imm12_pre(), etc.)
-** to virtual, so they can be overridden in MIPSAssembler. The implementation of these
-** functions on ARM is moved from ARMAssemblerInterface.cpp to ARMAssembler.cpp, and
-** is unchanged from the original. (This required duplicating 2 of these as static
-** functions in ARMAssemblerInterface.cpp so they could be used as static initializers).

-/* mips assembler
-** this is a subset of mips32r2, targeted specifically at ARM instruction
-** replacement in the pixelflinger/codeflinger code.
-**
-** To that end, there is no need for floating point, or priviledged
-** instructions. This all runs in user space, no float.
-**
-** The syntax makes no attempt to be as complete as the assember, with
-** synthetic instructions, and automatic recognition of immedate operands
-** (use the immediate form of the instruction), etc.
-**
-** We start with mips32r1, and may add r2 and dsp extensions if cpu
-** supports. Decision will be made at compile time, based on gcc
-** options. (makes sense since android will be built for a a specific
-** device)

- * General instruction format
- *
- *	insn[cc][mod]	[operands]
- *
- * Those fields with an uppercase format code indicate that the field
- * follows directly after the instruction before the separator i.e.
- * they modify the instruction rather than just being an operand to
- * the instruction. The only exception is the writeback flag which
- * follows a operand.
- *
- *
- * 2 - print Operand 2 of a data processing instruction
- * d - destination register (bits 12-15)
- * n - n register (bits 16-19)
- * s - s register (bits 8-11)
- * o - indirect register rn (bits 16-19) (used by swap)
- * m - m register (bits 0-3)
- * a - address operand of ldr/str instruction
- * e - address operand of ldrh/strh instruction
- * l - register list for ldm/stm instruction
- * f - 1st fp operand (register) (bits 12-14)
- * g - 2nd fp operand (register) (bits 16-18)
- * h - 3rd fp operand (register/immediate) (bits 0-4)
- * j - xtb rotate literal (bits 10-11)
- * i - bfx lsb literal (bits 7-11)
- * w - bfx width literal (bits 16-20)
- * b - branch address
- * t - thumb branch address (bits 24, 0-23)
- * k - breakpoint comment (bits 0-3, 8-19)
- * X - block transfer type
- * Y - block transfer type (r13 base)
- * c - comment field bits(0-23)
- * p - saved or current status register
- * F - PSR transfer fields
- * D - destination-is-r15 (P) flag on TST, TEQ, CMP, CMN
- * L - co-processor transfer size
- * S - set status flag
- * P - fp precision
- * Q - fp precision (for ldf/stf)
- * R - fp rounding
- * v - co-processor data transfer registers + addressing mode
- * W - writeback flag
- * x - instruction in hex
- * # - co-processor number
- * y - co-processor data processing registers

-/* To understand the values here, have a look at:
- *     system/core/include/private/pixelflinger/ggl_context.h
- *
- * Especially the lines defining and using GGL_RESERVE_NEEDS
- *
- * Quick reminders:
- *   - the last nibble of the first value is the destination buffer format.
- *   - the last nibble of the third value is the source texture format
- *   - formats: 4=rgb565 1=abgr8888 2=xbgr8888
- *
- * In the descriptions below:
- *
- *   SRC      means we copy the source pixels to the destination
- *
- *   SRC_OVER means we blend the source pixels to the destination
- *            with dstFactor = 1-srcA, srcFactor=1  (premultiplied source).
- *            This mode is otherwise called 'blend'.
- *
- *   SRCA_OVER means we blend the source pixels to the destination
- *             with dstFactor=srcA*(1-srcA) srcFactor=srcA (non-premul source).
- *             This mode is otherwise called 'blend_srca'
- *
- *   clamp    means we fetch source pixels from a texture with u/v clamping
- *
- *   mod      means the source pixels are modulated (multiplied) by the
- *            a/r/g/b of the current context's color. Typically used for
- *            fade-in / fade-out.
- *
- *   dither   means we dither 32 bit values to 16 bits

-# Unwinder Support Per Android Release
-This document describes the changes in the way the libunwindstack
-unwinder works on different Android versions. It does not describe
-every change in the code made between different versions, but is
-meant to allow an app developer to know what might be supported
-on different versions. It also describes the different way an unwind
-will display on different versions of Android.
-
-## Android P
-libunwindstack was first introduced in Android P.
-
-* Supports up to and including Dwarf 4 unwinding information.
-  See http://dwarfstd.org/ for Dwarf standards.
-* Supports Arm exidx unwinding.
-* Supports the gdb JIT unwinding interface, which is how ART creates unwinding
-  information for the JIT'd Java frames.
-* Supports special frames added to represent an ART Java interpreter frame.
-  ART has marked the dex pc using cfi information that the unwinder
-  understands and handles by adding a new frame in the stacktrace.
-
-## Note
-By default, lld creates two separate maps of the elf in memory, one read-only
-and one read/executable. The libunwindstack on P and the unwinder on older
-versions of Android will not unwind properly in this case. For apps that
-target Android P or older, make sure that `-Wl,--no-rosegment` is
-included in linker arguments when using lld.
-
-## Android Q
-* Fix bug (b/109824792) that handled load bias data incorrectly when
-  FDEs use pc relative addressing in the eh\_frame\_hdr.
-  Unfortunately, this wasn't fixed correctly in Q since it assumes
-  that the bias is coming from the program header for the executable
-  load. The real fix was to use the bias from the actual section data and
-  is not completely fixed until Android R. For apps targeting Android Q,
-  if it is being compiled with the llvm linker lld, it might be necessary
-  to add the linker option `-Wl,-zseparate-code` to avoid creating an elf
-  created this way.
-* Change the way the exidx section offset is found (b/110704153). Before
-  the p\_vaddr value from the program header minus the load bias was used
-  to find the start of the exidx data. Changed to use the p\_offset since
-  it doesn't require any load bias manipulations.
-* Fix bug handling of dwarf sections without any header (b/110235461).
-  Previously, the code assumed that FDEs are non-overlapping, and the FDEs
-  are always in sorted order from low pc to high pc. Thus the code would
-  read the entire set of CIEs/FDEs and then do a binary search to find
-  the appropriate FDE for a given pc. Now the code does a sequential read
-  and stops when it finds the FDE for a pc. It also understands the
-  overlapping FDEs, so find the first FDE that matches a pc. In practice,
-  elf files with this format only ever occurs if the file was generated
-  without an eh\_frame/eh\_frame\_hdr section and only a debug\_frame. The
-  other way this has been observed is when running simpleperf to unwind since
-  sometimes there is not enough information in the eh\_frame for all points
-  in the executable. On Android P, this would result in some incorrect
-  unwinds coming from simpleperf. Nearly all crashes from Android P should
-  be correct since the eh\_frame information was enough to do the unwind
-  properly.
-* Be permissive of badly formed elf files. Previously, any detected error
-  would result in unwinds stopping even if there is enough valid information
-  to do an unwind.
-  * The code now allows program header/section header offsets to point
-    to unreadable memory. As long as the code can find the unwind tables,
-    that is good enough.
-  * The code allows program headers/section headers to be missing.
-  * Allow a symbol table section header to point to invalid symbol table
-    values.
-* Support for the linker read-only segment option (b/109657296).
-  This is a feature of lld whereby there are two sections that
-  contain elf data. The first is read-only and contains the elf header data,
-  and the second is read-execute or execute only that
-  contains the executable code from the elf. Before this, the unwinder
-  always assumed that there was only a single read-execute section that
-  contained the elf header data and the executable code.
-* Build ID information for elf objects added. This will display the
-  NT\_GNU\_BUILD\_ID note found in elf files. This information can be used
-  to identify the exact version of a shared library to help get symbol
-  information when looking at a crash.
-* Add support for displaying the soname from an apk frame. Previously,
-  a frame map name would be only the apk, but now if the shared library
-  in the apk has set a soname, the map name will be `app.apk!libexample.so`
-  instead of only `app.apk`.
-* Minimal support for Dwarf 5. This merely treats a Dwarf 5 version
-  elf file as Dwarf 4. It does not support the new dwarf ops in Dwarf 5.
-  Since the new ops are not likely to be used very often, this allows
-  continuing to unwind even when encountering Dwarf 5 elf files.
-* Fix bug in pc handling of signal frames (b/130302288). In the previous
-  version, the pc would be wrong in the signal frame. The rest of the
-  unwind was correct, only the frame in the signal handler was incorrect
-  in Android P.
-* Detect when an elf file is not readable so that a message can be
-  displayed indicating that. This can happen when an app puts the shared
-  libraries in non-standard locations that are not readable due to
-  security restrictions (selinux rules).
-
-## Android R
-* Display the offsets for Java interpreter frames. If this frame came
-  from a non-zero offset map, no offset is printed. Previously, the
-  line would look like:
-
-    #17 pc 00500d7a  GoogleCamera.apk (com.google.camera.AndroidPriorityThread.run+10)
-
-  to:
-
-    #17 pc 00500d7a  GoogleCamera.apk (offset 0x11d0000) (com.google.camera.AndroidPriorityThread.run+10)
-* Fix bug where the load bias was set from the first PT\_LOAD program
-  header that has a zero p\_offset value. Now it is set from the first
-  executable PT\_LOAD program header. This has only ever been a problem
-  for host executables compiled for the x86\_64 architecture.
-* Switched to the libc++ demangler for function names. Previously, the
-  demangler used was not complete, so some less common demangled function
-  names would not be properly demangled or the function name would not be
-  demangled at all.
-* Fix bug in load bias handling. If the unwind information in the eh\_frame
-  or eh\_frame\_hdr does not have the same bias as the executable section,
-  and uses pc relative FDEs, the unwind will be incorrect. This tends
-  to truncate unwinds since the unwinder could not find the correct unwind
-  information for a given pc.

-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of

-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-General options:
-  -b, --buffer=<buffer>       Request alternate ring buffer(s):
-                                main system radio events crash default all
-                              Additionally, 'kernel' for userdebug and eng builds, and
-                              'security' for Device Owner installations.
-                              Multiple -b parameters or comma separated list of buffers are
-                              allowed. Buffers are interleaved.
-                              Default -b main,system,crash,kernel.
-  -L, --last                  Dump logs from prior to last reboot from pstore.
-  -c, --clear                 Clear (flush) the entire log and exit.
-                              if -f is specified, clear the specified file and its related rotated
-                              log files instead.
-                              if -L is specified, clear pstore log instead.
-  -d                          Dump the log and then exit (don't block).
-  --pid=<pid>                 Only print logs from the given pid.
-  --wrap                      Sleep for 2 hours or when buffer about to wrap whichever
-                              comes first. Improves efficiency of polling by providing
-                              an about-to-wrap wakeup.
-
-Formatting:
-  -v, --format=<format>       Sets log print format verb and adverbs, where <format> is one of:
-                                brief help long process raw tag thread threadtime time
-                              Modifying adverbs can be added:
-                                color descriptive epoch monotonic printable uid usec UTC year zone
-                              Multiple -v parameters or comma separated list of format and format
-                              modifiers are allowed.
-  -D, --dividers              Print dividers between each log buffer.
-  -B, --binary                Output the log in binary.
-
-Outfile files:
-  -f, --file=<file>           Log to file instead of stdout.
-  -r, --rotate-kbytes=<n>     Rotate log every <n> kbytes. Requires -f option.
-  -n, --rotate-count=<count>  Sets max number of rotated logs to <count>, default 4.
-  --id=<id>                   If the signature <id> for logging to file changes, then clear the
-                              associated files and continue.
-
-Logd control:
- These options send a control message to the logd daemon on device, print its return message if
- applicable, then exit. They are incompatible with -L, as these attributes do not apply to pstore.
-  -g, --buffer-size           Get the size of the ring buffers within logd.
-  -G, --buffer-size=<size>    Set size of a ring buffer in logd. May suffix with K or M.
-                              This can individually control each buffer's size with -b.
-  -S, --statistics            Output statistics.
-                              --pid can be used to provide pid specific stats.
-  -p, --prune                 Print prune rules. Each rule is specified as UID, UID/PID or /PID. A
-                              '~' prefix indicates that elements matching the rule should be pruned
-                              with higher priority otherwise they're pruned with lower priority. All
-                              other pruning activity is oldest first. Special case ~! represents an
-                              automatic pruning for the noisiest UID as determined by the current
-                              statistics.  Special case ~1000/! represents pruning of the worst PID
-                              within AID_SYSTEM when AID_SYSTEM is the noisiest UID.
-  -P, --prune='<list> ...'    Set prune rules, using same format as listed above. Must be quoted.
-
-Filtering:
-  -s                          Set default filter to silent. Equivalent to filterspec '*:S'
-  -e, --regex=<expr>          Only print lines where the log message matches <expr> where <expr> is
-                              an ECMAScript regular expression.
-  -m, --max-count=<count>     Quit after printing <count> lines. This is meant to be paired with
-                              --regex, but will work on its own.
-  --print                     This option is only applicable when --regex is set and only useful if
-                              --max-count is also provided.
-                              With --print, logcat will print all messages even if they do not
-                              match the regex. Logcat will quit after printing the max-count number
-                              of lines that match the regex.
-  -t <count>                  Print only the most recent <count> lines (implies -d).
-  -t '<time>'                 Print the lines since specified time (implies -d).
-  -T <count>                  Print only the most recent <count> lines (does not imply -d).
-  -T '<time>'                 Print the lines since specified time (not imply -d).
-                              count is pure numerical, time is 'MM-DD hh:mm:ss.mmm...'
-                              'YYYY-MM-DD hh:mm:ss.mmm...' or 'sssss.mmm...' format.
-  --uid=<uids>                Only display log messages from UIDs present in the comma separate list
-                              <uids>. No name look-up is performed, so UIDs must be provided as
-                              numeric values. This option is only useful for the 'root', 'log', and
-                              'system' users since only those users can view logs from other users.

-// prune "pruneRows" of type "id" from the buffer.
-//
-// This garbage collection task is used to expire log entries. It is called to
-// remove all logs (clear), all UID logs (unprivileged clear), or every
-// 256 or 10% of the total logs (whichever is less) to prune the logs.
-//
-// First there is a prep phase where we discover the reader region lock that
-// acts as a backstop to any pruning activity to stop there and go no further.
-//
-// There are three major pruning loops that follow. All expire from the oldest
-// entries. Since there are multiple log buffers, the Android logging facility
-// will appear to drop entries 'in the middle' when looking at multiple log
-// sources and buffers. This effect is slightly more prominent when we prune
-// the worst offender by logging source. Thus the logs slowly loose content
-// and value as you move back in time. This is preferred since chatty sources
-// invariably move the logs value down faster as less chatty sources would be
-// expired in the noise.
-//
-// The first pass prunes elements that match 3 possible rules:
-// 1) A high priority prune rule, for example ~100/20, which indicates elements from UID 100 and PID
-//    20 should be pruned in this first pass.
-// 2) The default chatty pruning rule, ~!.  This rule sums the total size spent on log messages for
-//    each UID this log buffer.  If the highest sum consumes more than 12.5% of the log buffer, then
-//    these elements from that UID are pruned.
-// 3) The default AID_SYSTEM pruning rule, ~1000/!.  This rule is a special case to 2), if
-//    AID_SYSTEM is the top consumer of the log buffer, then this rule sums the total size spent on
-//    log messages for each PID in AID_SYSTEM in this log buffer and prunes elements from the PID
-//    with the highest sum.
-// This pass reevaluates the sums for rules 2) and 3) for every log message pruned. It creates
-// 'chatty' entries for the elements that it prunes and merges related chatty entries together. It
-// completes when one of three conditions have been met:
-// 1) The requested element count has been pruned.
-// 2) There are no elements that match any of these rules.
-// 3) A reader is referencing the oldest element that would match these rules.
-//
-// The second pass prunes elements starting from the beginning of the log.  It skips elements that
-// match any low priority prune rules.  It completes when one of three conditions have been met:
-// 1) The requested element count has been pruned.
-// 2) All elements except those mwatching low priority prune rules have been pruned.
-// 3) A reader is referencing the oldest element that would match these rules.
-//
-// The final pass only happens if there are any low priority prune rules and if the first two passes
-// were unable to prune the requested number of elements.  It prunes elements all starting from the
-// beginning of the log, regardless of if they match any low priority prune rules.
-//
-// If the requested number of logs was unable to be pruned, KickReader() is called to mitigate the
-// situation before the next call to Prune() and the function returns false.  Otherwise, if the
-// requested number of logs or all logs present in the buffer are pruned, in the case of Clear(),
-// it returns true.

-Auditd Daemon
-
-The audit daemon is a simplified version of its desktop
-counterpart designed to gather the audit logs from the
-audit kernel subsystem. The audit subsystem of the kernel
-includes Linux Security Modules (LSM) messages as well.
-
-To enable the audit subsystem, you must add this to your
-kernel config:
-CONFIG_AUDIT=y
-
-To enable a LSM, you must consult that LSM's documentation, the
-example below is for SELinux:
-CONFIG_SECURITY_SELINUX=y
-
-This does not include possible dependencies that may need to be
-satisfied for that particular LSM.

-# Log Compression instead of Chatty in Android S
-
-## The problem
-
-* Log buffer space is precious, but suffers from the tragedy of the commons
-* Log spam fills the buffers making them less useful in logcat/bugreports
-* “Spam” is often in the eye of the beholder: which messages are important depends on what you’re trying to debug
-
-## The idea
-
-* Chatty isn’t helping as much as we’d hoped, and is surprisingly expensive
-* Compress logs to make more efficient use of the buffer
-* Address the root cause of log spam at its source:
-    * Do not hide log spam at runtime, which de-incentivize fixes
-    * Add presubmit coverage similar to SELinux violations to keep log spam down
-
----
-
-## Chatty in Theory
-
-* Delete messages classified as spam to extend the range of logs from other sources
-* “Spam” defined as:
-    * Logs from UIDs whose logs consume over 12.5% of a log buffer
-    * Back-to-back exact duplicate messages
-
-## Chatty in Practice
-
-* Developer confusion about missing and de-duplicated logs
-* Lowered incentive to fix the root cause of bad logging behavior
-* High CPU overhead
-* Memory usage greatly exceeds configured buffer size
-* Only marginal increase in log range
-
----
-
-## Log Compression in Theory
-
-* Store many more logs in the same log buffer size => better for diagnosis
-* Memory usage stays below configured log size => better system health
-* No gaps in logs, no de-duplicated logs => no developer confusion
-* No hiding bad behavior => increased accountability/incentive to fix root causes
-
-## Log Compression Preliminary Results
-
-* Captured 2, 5 day periods of full time personal usage of Pixel 4 and replayed the logs offline
-* Compression vs Chatty:
-    * **3.5x more log messages on average**
-    * **50% less CPU usage**
-    * **50% less memory usage**
-
----
-
-## Log Messages in 1MB
-
-* The number of log messages still available in logcat after ‘Message Count’ messages have been logged to a 1MB log buffer
-* Note: ‘Simple’ is the Chatty code without log spam detection and without de-duplication.

-* Total CPU time on ARM64 (Walleye) and 32bit x86 (Cuttlefish)
-* X axis represents different log buffer size configurations.
-    * Chatty uses significantly more CPU time at 1MB (the default Pixel configuration)
-    * Chatty scales poorly with increased log buffer sizes
-* Note: “simple” isn’t “compression without actually compressing”, it’s “chatty without doing the chatty elimination”, which is why “simple” is more expensive than “compression” on walleye.

-
-## Memory Usage
-
-* The memory used by ‘Message Count’ messages, on both Walleye and Cuttlefish
-* Note: Chatty does not consider the metadata (UID, PID, timestamp, etc) in its calculation of log buffer size, so a 1MB log buffer will consume more than 1MB.  Note that there are 8 log buffers, 5 of which are typically filled.

-logd can record and replay log messages for offline analysis.
-
-Recording Messages
-------------------
-
-logd has a `RecordingLogBuffer` buffer that records messages to /data/misc/logd/recorded-messages.
-It stores messages in memory until that file is accessible, in order to capture all messages since
-the beginning of boot.  It is only meant for logging developers to use and must be manually enabled
-in by adding `RecordingLogBuffer.cpp` to `Android.bp` and setting
-`log_buffer = new SimpleLogBuffer(&reader_list, &log_tags, &log_statistics);` in `main.cpp`.
-
-Recording messages may delay the Log() function from completing and it is highly recommended to make
-the logd socket in `liblog` blocking, by removing `SOCK_NONBLOCK` from the `socket()` call in
-`liblog/logd_writer.cpp`.
-
-Replaying Messages
-------------------
-
-Recorded messages can be replayed offline with the `replay_messages` tool.  It runs on host and
-device and supports the following options:
-
-1. `interesting` - this prints 'interesting' statistics for each of the log buffer types (simple,
-   chatty, serialized).  The statistics are:
-    1. Log Entry Count
-    2. Size (the uncompressed size of the log messages in bytes)
-    3. Overhead (the total cost of the log messages in memory in bytes)
-    4. Range (the range of time that the logs cover in seconds)
-2. `memory_usage BUFFER_TYPE` - this prints the memory usage (sum of private dirty pages of the
-  `replay_messages` process).  Note that the input file is mmap()'ed as RO/Shared so it does not
-  appear in these dirty pages, and a baseline is taken before allocating the log buffers, so only
-  their contributions are measured.  The tool outputs the memory usage every 100,000 messages.
-3. `latency BUFFER_TYPE` - this prints statistics of the latency of the Log() function for the given
-  buffer type.  It specifically prints the 1st, 2nd, and 3rd quartiles; the 95th, 99th, and 99.99th
-  percentiles; and the maximum latency.
-4. `print_logs BUFFER_TYPE [buffers] [print_point]` - this prints the logs as processed by the given
-  buffer_type from the buffers specified by `buffers` starting after the number of logs specified by
-  `print_point` have been logged.  This acts as if a user called `logcat` immediately after the
-  specified logs have been logged, which is particularly useful since it will show the chatty
-  pruning messages at that point.  It additionally prints the statistics from `logcat -S` after the
-  logs.
-  `buffers` is a comma separated list of the numeric buffer id values from `<android/log.h>`.  For
-  example, `0,1,3` represents the main, radio, and system buffers.  It can can also be `all`.
-  `print_point` is an positive integer.  If it is unspecified, logs are printed after the entire
-  input file is consumed.
-5. `nothing BUFFER_TYPE` - this does nothing other than read the input file and call Log() for the
-  given buffer type.  This is used for profiling CPU usage of strictly the log buffer.

-# Tag names are one or more ASCII letters and numbers or underscores, i.e.

-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of

-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,

- *           NULL-terminated
- *   status: the equivalent child status as populated by wait(status). This
- *           value is only valid when logwrap successfully completes. If NULL
- *           the return value of the child will be the function's return value.
- *   forward_signals: set to true if you want to forward SIGINT, SIGQUIT, and
- *           SIGHUP to the child process, while it is running.  You likely do
- *           not need to use this; it is primarily for the logwrapper
- *           executable itself.
- *   log_target: Specify where to log the output of the child, either LOG_NONE,
- *           LOG_ALOG (for the Android system log), LOG_KLOG (for the kernel
- *           log), or LOG_FILE (and you need to specify a pathname in the
- *           file_path argument, otherwise pass NULL).  These are bit fields,
- *           and can be OR'ed together to log to multiple places.
- *   abbreviated: If true, capture up to the first 100 lines and last 4K of
- *           output from the child.  The abbreviated output is not dumped to
- *           the specified log until the child has exited.
- *   file_path: if log_target has the LOG_FILE bit set, then this parameter
- *           must be set to the pathname of the file to log to.
- *
- * Return value:
- *   0 when logwrap successfully run the child process and captured its status
- *   -1 when an internal error occurred
- *   -ECHILD if status is NULL and the child didn't exit properly
- *   the return value of the child if it exited properly and status is NULL
